DSH Artifact Promotion Proof
An offline, deterministic evidence layer for DeepSeek Harness supply chains. It checks whether one explicit artifact digest followed a declared build → staging → production chain with the exact environment bindings, predecessor receipts and gate evidence required at every stage.
It does not deploy anything, call a registry, grant approval, verify runtime health, or mutate an environment. It also does not authenticate receipts or verify provenance signatures. A promoted verdict means only that the supplied hash-only records are internally complete, ordered and policy-conformant.
Complementary boundary
dsh-release-proof compares download endpoints for HTTP, length, version and SHA-256 agreement.dsh-attestation-proof verifies DSSE/in-toto signatures, subjects and signer thresholds.dsh-reproducible-build-proof compares independent rebuild outputs.dsh-build-hermeticity-proof checks one recorded build's declared external-influence closure.dsh-output-custody-proof checks how a DSH tool result is projected, spilled and durably recorded.- This plugin checks zero-rebuild promotion continuity across declared deployment stages.
dsh-evidence-arena promotes a selected coding worktree into a repository; this plugin never writes a candidate or repository.
Every stage must appear exactly once and in order. The artifact digest, stage/environment hash and predecessor deployment receipt must remain continuous. Required gate types must appear once, bind the same artifact, precede promotion and meet the stage's distinct-authority threshold. Missing, stale, reordered, cross-artifact or extra gate evidence fails closed.
Install
dsh plugin --profile evidence add github:dongsheng123132/dsh-artifact-promotion-proof#COMMIT
The bundle exposes dsh_artifact_promotion_inspect and dsh_artifact_promotion_verify from one headless core. The independent MCP stdio server exposes artifact_promotion_inspect and artifact_promotion_verify. The CLI accepts inspect or verify plus an explicit JSON path.
See examples/promoted.json. Reports contain only hashes, counts, booleans, gate classifications and verdicts. Secret-shaped material and raw log/body/content fields are rejected. The DSH verify tool reads a workspace-relative non-symlink manifest, writes only to an explicit workspace-relative artifactDir, creates deterministic content-addressed output exclusively, and verifies it by read-back.
